Scenario
What this Use Case will teach you
At the end of this use case you will:
- understand how to access and collect data from Melbourne Open Data
- have explored datasets such as Pedestrian Counting System and sensor location
- learnt how to visualise data using different mapping visualisation techniques
A brief introduction to the datasets used
The City of Melbourne provides comprehensive pedestrian traffic data, as well as sensor location data. In this use case we will utilise the Pedestrian Counting System - Past Hour (counts per minute) dataset
This dataset contains minute-by-minute directional pedestrian counts from the last over from pedestrain sensor devices located across the city. The data is updated every 15 minutes and can be used to determinate variations in pedestrian activity throughout the day.
We also utilise the City of Melbourne's Sensor Locations dataset. This data will be used to extract the location of these sensors which helps with visualisation.
Accessing and Loading data
We aim to make a decision that will be informed by insights based on the latest data.
In order to get this data, we can create a function to extract, transform and load (ETL) pedestrian traffic data every 15 minutes.
First, we will do ETL for Sensor Locations and Pedestrian Counting System - Past Hour (counts per minute).
We will then merge these datasets.
Note: We use the package sodapy to extract from Melbourne Open Data directly. This package is a python client for the Socrata Open Data API. To extract the data from Melbourne Open Data, you must have a dataset id. It can be found as follows:

sensor_location["lat"] = sensor_location["lat"].apply(lambda x: float(x))
sensor_location["lon"] = sensor_location["lon"].apply(lambda x: float(x))

Using Selenium to Crawl Data
To help drive insight to informing our business scenario, we can compare the data from two different sensor locations.
This means we can compare pedestrian foot traffic in two separate locations over different periods of the current date, as well as over a 4-week period.
However, in order to get this data, we need to crawl the data from http://www.pedestrian.melbourne.vic.gov.au.
Note Because we cannot use Sodapy to crawl the data from this website, We use another package Selenium to extract the data.

Basic Map Visualisation
Visualising data provides an easy way for us to detect patterns within the data. Using the python library ipyleaflet, we can create a live pedestrian traffic map of the City of Melbourne.
This map will represent all of the data of the pedestrian sensor locations within the City of Melbourne.
This map is updated every 15 minutes for up-to-date pedestrian traffic information.
from ipyleaflet import Map, Marker, MarkerCluster, Circle, basemaps
#Make the output space to be larger
from IPython.core.display import display, HTML
display(HTML("<style>div.output_scroll { height: 1000px; }</style>"))
def map_visualization(data):
locations = []
for i in range(len(data)):
row =data.iloc[i]
location = [Marker(location=(row.lat,row.lon), title = row["Sensor Description"])]*int(row.Count)
locations += location
m = Map(basemap=basemaps.OpenStreetMap.Mapnik, center=[-37.8167, 144.967], zoom=15)
marker_cluster = MarkerCluster(markers=locations)
m.add_layer(marker_cluster)
#Make the output map to be larger
m.layout.width = '100%'
m.layout.height = '1000px'
return m
map_visualization(counting_data)
As we can see, the majority of the pedestrain traffic takes place around Swanston street in the heart of the city
Basic Trend Visualisation
Having developed a basic visualisation of our data, we can now produce a visualisation that shows us potential trends in pedestrian foot traffic.
We can create a line chart that consists of two lines of different sensor locations at different times of day.
Based on this visualiation, we can compare the rush hour and off-peak periods of the two sensors.
This information has the potential to help inform our business owner of his new potential location.

def trend_visualization(sensor_1, sensor_2, daily_data = daily_data, monthly_data = monthly_data):

daily_data_sensor_1 = daily_data[sensor_1]
monthly_data_sensor_1 = monthly_data[sensor_1]
daily_data_sensor_2 = daily_data[sensor_2]
monthly_data_sensor_2 = monthly_data[sensor_2]

#Show line chart of sensor 1 and 4

Based on this visualisation, if we want to open a business that caters for the lunch time crowd then we may wish to locate our business near Bourke street mall.
However, if we want to open a business that caters to the Dinner crowd, perhaps the area in and around Melbourne Central provides better incentives.
This goes to show just how dynamic life is in the City of Melbourne
Geographic Filter
Sometimes, we require more specific information that may not be obtainable from the sensor information alone. In this example, we take specific addresses as data input instead of the Sensor location to provide a more meaningful and insightful result.
We can create a Geographic Filter that will take a specific address such as 100 Flinders Street and create a live map and a live line chart.
The problem is that an address may have multiple pedestrian sensors near it. Therefore, we introduce another variable called Radius. This variable aims to filter all sensors that are within the radius of the target address
We then take a sum of these different sensors to access the pedestrian data of the address.
To produce this filter, we have 8 steps :
- Take addesses
- Use Google API to get the information about Latitude and Longtitude of these addresses
- Find the distance between these addresses and the sensors
- Filter sensors are near these addresses
- Create a live chart
- Filter daily and monthly data
- Draw a line chart
